A smoke characterization study finished earlier this year prompted the International Association of Fire Chief's Fire and Life Safety Section issued recommendations to fire departments concerning the use of smoke alarms.

The study, conducted by Underwriters Laboratories and the National Fire Protection Association's Fire Protection Research Foundation, identifies differences and advantages to the two types of alarms in detecting smoke. Both ionization and photoelectric detectors are sold the public for residential installation. FLSS recommends that dual alarms using both technologies be installed for maximum protection.

"We recognize that many departments in the United States have residential safety programs where they offer and install alarms at no charge," said Steven Westermann, IAFC president. "We suggest departments continue their programs with the alarms they have on-hand, but we recommend that they upgrade to the dual-technology devices when it’s time to restock.

"Life safety is an integrated strategy. Use the information in the FLSS position paper as part of your education plan to your community. Offer this as part of a comprehensive residential fire-protection program that includes integrating family-escape plans, proper usage of smoke alarms and installation of residential sprinkler systems," he said.

FLSS presents its detailed recommendations in a position paper, which was reviewed and approved by the IAFC board of directors. To view the position paper, go to iafc.org/flss
